I've been using Instagram in my iPhone 5s for a couple of years or more and I've never had any trouble but last month or so, Instagram asked me to log into my Facebook account to share my pictures there (as I've always have shared them) so it sent me to the Facebook link in Safari. But when I try to log into my account I get stuck in the logging in screen and can't log in. It seems like it's logging in but after it charges, I'm back at the same logging in page. I tried deleting Instagram and Facebook from my iPhone but I still have the problem. And I checked if it was just when I tried to log in to connect my Instagram account to the Facebook one but if I try to log into Facebook through Safari I have the same problem.
